The chief feature of the inventionconsists of the dewateringyor draining` mechanism which permits successful and relativelyrapid drainage of substantially the entire free Wa;- v

"515 ter .contentof .the tankage, whereby the de.-

- watered tankage may: thereafter, in the same tank, be dried (and retained in siiitableforin) forsubsequent voperation `as claimed in the Vcopending`continuationfin-p'a'rt application @i SerialNo;` 698,106, which otherwise Wouldv b e iin-possible if the free, Water content Was not substantially and entirely rernovedA from taifikage, if derived from garbage vandthe like.

theagitator 49 started andthe operationcon` tinued until the ydrying is completed. The vacuum tobe applied varies with'the nature of the material being treated but any vacuum that can be produced by mechanical means During the drying processthe organic material mostr desired is disintegrated, shredded and torn into small pa-rtiy i cles by the action of thev agitator while the foreign matter such as metals, glass, crock-` ery,wood, rags, strings and the like are left in substantially the same condition and size as when placed in the tank, thus preparing the treated garbage which now becomesdrie'd tankage forthe next, step in the process, The vacuum is now broken, the discharge door 34 y opened and' the agitator, is rotated to assist in'the'discharge ofi the tankage. lThe tank-V age is then allowed to cool which may be has? tened by spreading it Yout so as to expose it to the air.

It is to be understood also that the device Y is not limited. inuse to garbage reduction, but

may be applied to other uses for which it isA or may be found suited, and that, therefore, throughout the specification and claims' the term garbage is to be interpreted as meaning any substance for the reduction and separation of which the invention may be y yada ted.
